Embedded Software Test: Best Practices for Unit/ Module /Component Testing - Live Online Training

Content

Development and Test Process in the W-Model (V-Model Extension)

• Development stages: analysis, design, implementation
• Test stages: component test, integration test, system test, acceptance test
• Test types: functional, non-functional, structure-oriented test
• Post test, regression test, maintenance test
• Standards relevant to testing
• Developing testable software
• Definition of terms: unit, module, component
• Difference between debugging and testing

Static Tests

• Review process: document review, coder review, inspection, walkthrough
• Tool-aided static code analysis

Dynamic Tests

• Blackbox: equivalence class construction, threshold testing, decision table testing, state transition testing, use case testing
• Whitebox: statement testing/ coverage, decision testing/ coverage, condition testing/ coverage
• Experience-based techniques: error guessing, explorative testing
• Systematic approaches for developing test cases
• Selection criteria for test methods
• Test method assessment

Code Metrics

• Lines of code, cyclomatic number according to McCabe, Halstead metric
• Using metrics in the test process

Design for Test

• S.O.L.I.D. principles
• Single responsibility, open closed
• Liskov substitution
• Interface segregation, dependency inversion

Testing Object-Oriented Software

• Testing class hierarchies
• Testing methods of a class
• Testing class relations
• Testing inheritance
• Testing polymorphic class hierarchies

Test-Driven Development, TDD

• Advantages of TDD
• Embedded TDD strategies
• TDD example

Integration of System Components - Overview

• Integration test, system test, acceptance test

Integration of Hardware and Software

• Test execution on hardware

Further Activities in the Test Process - Overview

• Test management, planning, control
• Risk management, fault and incident management
• Configuration management and version control
• Software quality features according to ISO 9126
• Test documents according to IEEE 829
• Test tools types, selection, implementation

Hands-on Exercises

• Exercises on test analysis, test design, test implementation, test execution, test report
• Execution of code Review
• Execution of blackbox and whitebox tests with Tessy, with and without HW
• Test data determination using the classification tree method with CTE
• Determining code metrics using the tools cccc and CMT++
• Using Google Test and Google Mock
• The Arm/ Keil µVision and a Cortex™-M evaluation board are used for tests on HW
